SUMMARY OF THE INVENTION

A new coil carrier intermodal shipping container has a maximum gross weight based with a strongly supported base and truss-shaped downward and inward sloping coil supports positioned on the base.

The new intermodal shipping container coil carrier for steel sheet rolls has a strong base of longitudinal I-beams, joined by cross beams, box beams along sides and ends and a strong steel deck. Spaced opposite downward and inward sloping supports are mounted on trusses extending upward from the steel deck. The trusses have strong bases extending along the deck, strong sloping legs joined at right angles and stronger vertical inner legs that extend through the steel deck and are joined to the major supporting beams in the base. Five or more similar trusses hold the inward sloping opposite supports. The sloping supports are formed as box beams with inner reinforcements and are held on inward and downward sloping legs.

The coil-carrying intermodal shipping container has upper and lower corner fittings connected at corners of the base. The lower corner fittings are corner castings configured for connection with twist locks to fixed corner castings of cargo carrying decks of trailers, railroad cars or ships. When unloaded the intermodal shipping containers or their bases may be stacked and secured in the stacks with twist locks.

The upper corner fittings on the container base are upper corner casings with permanently installed twist locks configured for connecting to lower corner fittings at corners of a three-dimensional lid. The permanently installed twist locks hold an open bottom of the lid tightly on a periphery of the container base, completing the intermodal shipping container.

The cover lid has at its four corners heavy duty vertical box beam corner posts with upper and lower corner castings attached to each post. Upper side and end beams connect the corner posts at their tops. Lower side and end beams connect the vertical corner posts near their lower ends. The lower corner castings of the lids are connected with the permanently installed twist locks in the base vertical corner casings.

A coil carrying intermodal shipping container has a strongly supported base with plural longitudinal steel I beams and plural transverse steel I beams connected to the longitudinal I beams. Corner connectors are connected at corners of the base to ends of outermost longitudinal I beams and to ends of outermost transverse I beams. The corner connectors have upper corner fittings and lower corner fittings. Twist locks are permanently monitored in the upper corner fittings. A deck is connected to the longitudinal I beams. Coil carriers are mounted on the deck and are connected to the longitudinal I beams. The coil carriers have pairs of inward and downward sloping coil supports on inward and downward sloping inner beams connected at tops to longer outer legs and at bottoms to shorter inner legs. The shorter inner legs are connected to the longitudinal I beams.

The coil carrying intermodal shipping container has a three dimensional lid with vertical corner posts. The corner posts have upper corner castings and lower corner castings connected to each of the corner posts. The lower corner castings on the corner posts are connectable to the upper fittings on the corner connectors on the base. The lid has vertical sides with vertical longitudinal ends connected to the corner posts. The lid has vertical ends with vertical lateral edges connected to the corner posts. The lid has a top roof connected along its edges and corners to tops of the vertical sides, tops of the vertical ends and to tops of the vertical corner posts. The lid has an open bottom with edges configured for sealing with edges of the base when the twist locks are engaged.

Coil carriers have spaced paired inward sloping support beams, outer legs sloping outward from their tops and horizontal links connecting them, forming trusses. Inner legs connected to the trusses extend through the deck and connect to the longitudinal I beams. There are at least six trusses in each pair of coil supports.

Three coil carriers are mounted on the deck. Fastening pins beneath the openings in the deck are connected to the longitudinal beams for securing straps around coils supported on the coil carriers.

These and further and other objects and features of the invention are apparent in the disclosure, which includes the above and ongoing written specification, with the claims and the drawings.

DETAILED DESCRIPTION

FIG. 1 is a side view of the intermodal shipping container. The container 1 has a maximum strength base 10 formed of plural parallel I-beams 11 running in the longitudinal direction and plural cross beams 13 welded to the longitudinal I-beams. Side and

end box beams

15 and 17 are welded at sides and ends of the support beams in the base 11. Fork lift tunnels 19 are provided through the lateral I-beams and side beams for lifting the container when empty.

In a covering lid 20, vertical corner post beams 21 are welded to the I-beams at lower corners 22 of the container lid 20. Lower corner fittings 31 are connected at intersections of lower side beams, lower end beams and lower ends of the vertical corner post beams 21. Upper corner fittings 32 are welded to tops of the corner beams 21. Ends of upper longitudinal beams 33 and upper end beams 35 are welded to the upper corner fittings 32. Corrugated sides, ends and a roof are connected and sealed to the beams to make the lid of the intermodal shipping container moisture tight.

A deck 40 is supported on the strong base 10. Deck 40 has a strong steel surface connected to the parallel I-beams and cross beams. Deck 40 has welded side and

end box beams

15 and 17. Deck upper corner casings 51 are connected to upper corners of the side and

end beams

15 and 17. The deck upper corner casings 51 are connectable to the lid 20

lower corner fittings

31 with twist locks 52 permanently installed in the corner casings 51. The lower corners of the deck have lower corner castings 53 that are connected to fixed corner castings on trailers, train cars and ships with twist locks for intermodal transportation.

The strong steel deck 40 has a surface supported by the beams of the base 10. Coils 80 of steel sheets are held in the container 1 on sloping supports 60. The sloping supports 60 are mounted on spaced-apart steel beam trusses 61. Trusses 61 have inner vertical legs 63 that extend downward through the deck 40. Lower ends 64 of the legs 63 are attached to and supported on the longitudinal and cross

beams

11, 13 of the base 10. Outward and downward sloping outer legs 93 have upper ends 92 attached to the inward and downward sloping supports 60. Lower ends 94 of the outer legs are attached to links 95 that complete the trusses 61. Five or more trusses support each elongated box beam 65 with flat surfaces 67 and inner supports 69. Two oppositely inward sloping box beams 65 support one coil 80.

In openings of the deck the longitudinal base beams 11 hold depressed fastening pins 72. Straps are placed around the coils 80 and fastened to the pins 72 before closing the lid on the container.

The fork lift tunnels 19, as shown in FIGS. 1 and 4 , are intended for use to move the heavyweight container 1 before coils 80 are loaded on the supports 60 and after the coils 80 are individually removed from the base 10 of container 1.

In operation the base 10 of an empty container is lifted on a trailer platform with a forklift and is connected with twist locks. The coils 80 are placed one by one with a forklift having a coil lifting attachment. The coils are strapped down. Then the lid 20 is lifted with a forklift and lowered onto the base. The lid and base are locked and sealed together with four corner twist locks permanently mounted within the vertical upper corner casings of the base.

When the container is secured on a ship, the sheet steel rolls 80 in an intermodal shipping container 1 are placed and locked on the ship's hold bottom or deck before additional lighter containers are supported atop the sheet steel rolls containers 1.

While the invention has been described with reference to specific embodiments, modifications and variations of the invention may be constructed without departing from the scope of the invention, which is defined in the following claims.
